Dish recently told NCR that it was time to pull the plug on their licensing agreement for the Blockbuster Express kiosks, a move that has led NCR to file a lawsuit.

Per the rules of Bankruptcy Court, new owner Dish does have the right to accept or reject the contracts signed by Blockbuster before the sale. But according to a report in the L.A. Times, NCR says that the trust set up to administer Blockbuster’s intellectual property rights lacks the grounds to end the licensing agreement.

The kiosk company, which currently operates around 9,000 Blockbuster Express machines, says that ending the licensing deal will cause NCR “substantial hardship and irreparable harm.”
